Application of a Self-Similar Pressure Profile to Sunyaev-Zel'dovich Effect Data from Galaxy Clusters
T. Mroczkowski, M. Bonamente, J. E. Carlstrom +16
We investigate the utility of a new, self-similar pressure profile for fitting Sunyaev-Zel'dovich (SZ) effect observations of galaxy clusters. Current SZ imaging instruments - such…
Observations of High-Redshift X-Ray Selected Clusters with the Sunyaev-Zel'dovich Array
Stephen Muchovej, John E. Carlstrom, John Cartwright +14
We report measurements of the Sunyaev-Zel'dovich (SZ) effect in three high-redshift (0.89 < z < 1.03), X-ray selected galaxy clusters. The observations were obtained at 30 GHz duri…
How accurately can suborbital experiments measure the CMB?
Angelica de Oliveira-Costa, Max Tegmark, Mark Devlin +4
Great efforts are currently being channeled into ground- and balloon-based CMB experiments, mainly to explore anisotropy on small angular scales and polarization. To optimize instr…
Comparing and combining the Saskatoon, QMAP and COBE CMB maps
Yongzhong Xu, Max Tegmark, Angelica de Oliveira-Costa +5
We present a method for comparing and combining maps with different resolutions and beam shapes, and apply it to the Saskatoon, QMAP and COBE/DMR data sets. Although the Saskatoon…
Galactic contamination in the QMAP experiment
Angelica de Oliveira-Costa, Max Tegmark, Mark J. Devlin +6
We quantify the level of foreground contamination in the QMAP Cosmic Microwave Background (CMB) data with two objectives: (a) measuring the level to which the QMAP power spectrum m…
Mapping the CMB III: combined analysis of QMAP flights
Angelica de Oliveira-Costa, Mark Devlin, Tom Herbig +4
We present results from the QMAP balloon experiment, which maps the Cosmic Microwave Background (CMB) and probes its angular power spectrum on degree scales. In two separate flight…
